After choosing which sets i want to use the installer starts to download them.
Halfway through comp45 i get different errors and i mean always different.
This last time i get this: (i will post more errors as i get them)

id 0 on /mnt: write failed, file system is full
tar: Failed write to file ./insert_random_file: No space left on device

Solved it but thanks for help anyway. Was some sort of irq conflict that made the satacontroller go crazy. A hint was searching google with "abit nf7-s booting from sata drive" and getting ALOT on hits...
